To read the original full thread and post questions/comments, please go to Converting the mirror lights to turn signal lights (basic overview w/ pics)
Did you ever want to convert your white mirror lights to amber turn signal lights? I did! So here are some basic details.
Note 1: I currently have another post going for heated mirror installation and both of these projects are running concurrently. I am going to do a brief thread here on the signal lights only.
Note 2: Pretty involved project by itself. You would need to want these pretty bad to do it by itself. But what the heck, doing a little project like this is kinda fun.
Step 1:
might as well start with the signal taps. you will need to tap a pink line for a right hand signal and tap a blue w/ white stripe line for the left signal. the taps will need to be "after" the signal relay up under the drivers side dash.
Step 2:
make your t-splices as mentioned above
Note: I'm sure there are other locations to make your taps, this location seemed convenient to me.
Step 3:
take your door panel off, remove the kick panel and door sill molding
Note: make sure the window is in the "up" postion (learned the hard way)
Step 4:
remove the speaker (this is to allow access for a few of the following steps)
Step 5:
remove the access cover to the mirror
Step 6:
remove the mirror (3 screws and a little plastic clippy thing) Note: this is the area where you will apreciate having the window up in step #3 (CRAP!)
Step 7:
remove the plug/metal bracket on the mounting surface of the mirror
Step 8:
pull off the rubber gasket on the mirror base to expose "path" to mirror body.
Note: set the mirror down, we are done with that for a while
Step 9:
remove the door wire harness bracket from the door (this will allow access to the wire "tube" that runs from the door into the cabin
Step 10:
fish a positive line and a negative line for the light thru the wire "tube" into the cab. I used yellow for positive and black for negative. Note: You may see the additional wires I ran for the heaters also, they are red and black
Step 11:
reinstall the door wire harness bracket and tidy up the wires leading into the mirror access hole. Note: on a project like this, don't be a cheap a$$. allow more than ample wire on both ends to reach your destination with extra wire to trim off.
Step 12:
run the wires through the door and out the mirror hole. Note: be very carefull how you route the wires in the door. make sure they route out of harms way of the window
Step 13:
fish the wires into/through the mirror (see also step #8) and remount the mirror. Note: this is a step where you will need an extra set of hands to hold the mirror and remount it. thank goodness my wife got home at the exact moment I was doing this and my left arm was giving out (what are the odds?)
Step 14:
cut the 2 wires on the mirror light and connect 1 of them to the new "power" "yellow" line and connect the other cut line to the ground "black" line.
I appolgize - did not get a picture here, but pretty straight forward
Step 15:
put everything back together and throw away any left over "extras"

(i.e. hide the evidence)
Step 16:
run the new power (yellow) and ground (black) over to the taps made in step #2. Plug in the "yellow" lines to the "pink" and "blue/white" taps. connect the black lines to ground.
(sorry no pic again)
Step 17:
repeate steps #1 - #16 for the "other" side
Step 35:
have a beer and pat yourself on the back ..... job is done.
caught a pic right as the amber bulb was in the "signal on" postion
I am sure most of you will say "heck of a lotta work for turn signals?" ...
I say "personalize!"
